Characteristics of Temperature and Wind Speed at the Liangcheng Venue of the 14th National Winter Games in China
In order to know the weather characteristics of the Liangcheng venue area for the 14th National Winter Games,and to provide a reference for the weather review and summary of this Winter Games as well as a basis for meteorological services for future Winter Games,the distribution characteristics of temperature and wind speed were analyzed based on the meteorological observation data of the Liangcheng competition venue from December 2023 to February 2024.The results indicated that:(1)The daytime temperature variation in the venue was primarily influenced by solar radiation,and was indirectly affected by factors such as terrain and elevation which could influence solar radiation intensity and duration,while the nighttime temperature variation was affected by them insignificantly.Notable temperature changes occurred after 08:00 and 14:00 at all stations,but the magnitude of these changes did not vary significantly with altitude.(2)The wind speed variation in the competition area was influenced by factors such as solar radiation,terrain,and altitude.The wind speed exhibited phased characteristics,with the all-day wind speeds at the mountaintop stations SD and QD being significantly higher than those at the other five stations.The wind speed at station SD decreased starting from 09:00 and increased starting from 13:00,while the wind speed at station QD remained relatively stable throughout the day.In contrast,the wind speed at the stations located on mountain slopes and in valleys was higher during the daytime and lower at night.Additionally,the wind speed distribution at stations below 1500 m in altitude was more concentrated,while it was relatively dispersed at other stations.
